CO is a very agressive reg who Cbets alot; VP 22, PFR 18, CBetF 78, AF 7
I considered 3betting this hand PF, because of the pretty wide opening range of the CO, I guess 3 betting PF here is correct also yes?

I decided to fold the overpair because of the CBet against 4 opponents and I was almost sure that he would bet the turn again, was this fold too weak?

Welcome to the English NL Hand Evaluation Forum! Hopefully we will see more hands from you in the future. I hope that with our help you can improve your play and as well move up the limits. We will be waiting for the next hands and till that good luck on tables!

Add to full stack by the way if you playing BSS, try to keep 100bb.

Preflop: Though I would rather call it whilst we have position and may also invite some bad players come along.
We can't really 3bet it for value cause I assume you have to 3bet/Fold it.Postflop: Not much to comment, he is also CBetting into such a mutliway pot, I doubt that you going to see like tons of worse hands.
